To all whom 'it may concern:

Be it known that I, JOHN B. LIVINGSTON, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Percolators; and I do hereby declare the following, when taken in connection with the accompanying drawin s and the numerals of reference marked t ereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1 a side view partially in section of a percolator constructed in accordance with my invention. Fig. 2 a broken lan view showing the support at one en of the steam-pipe supportmg irons. Fig. 3 a broken front end view. Fig. 4 a broken sectional view of the bottom of the casing. Fig. 5 an enlarged end view of one of the steam pipes. F 1g. 6 a sectional View of the Fig. 7 a broken transverse sectional view through the front end of the casing. Fig. 8 a top or plan view of a portion of the bottom.

This invention relates to an improvement in percolators for treating garbage, fish and animal tankage, or similar material. To remove the grease the tankage is washed with naphtha, and then to save the naphtha which does not drain ofi with the fat, the naphtha is steamed out and reclaimed.

The object of this invention is to provide a percolator in which the grease may be readily extracted from the tankage, from which the un-used naphtha may be reclaimed, and which may be readily emptied; and the invention consists in the construction hereinafter described and particularly recited in the claims.

In carrying out my invention, I employ a barrel-like casing 2 having annular bands 3, 4, which ride on rollers 5, 6, at op osite ends so that the barrel may be rotate As herein shown one end of the barrel is provided with an annular rack 7 which meshes with a gear 8 on a driving shaft 9, and so that turning the gear will rotate the barrel. In the top of the barrel are suitable man holes 10 and 11 closed 'by suitable covers 12. Extending longitudinally of the casin and inside the same are a series of channe bars 13 resting at one end upon brackets 14, and

riveted at that end to the end 15 of the easing. These channel bars are shorter than the length of the casing and at their opposite en s are supported between brackets 16 and 17, and formed with slots 19 through which the retaining rivets 20 .pass so that the channel bars may expand or contract longitudinally. These channel bars are in turn supported by transverse I beams 21. These at one end rest on brackets 22 secured to the sides of the casing, and at the opposite end rest on brackets 23' to which they are bolted, the bolts passing through slots 24 in the bracket so as to permit of contraction and expansion.

In the bottom-0f the tank are a series of transverse partitions 25, forming a series of chambers, each alternate partition being cut out to allow liquid to pass under it, and on these partitions rest a perforated bottom 26,- v

which is preferably covered with cloth 27 or other suitable material which acts as a strainer, and over this cloth is placed a strip of wire-netting or wire screen cloth 28, the cloth and gunny sack being held in position by strips 29 which are bolted through the perforated plate to the partitions 25. At the top of the casing is an outlet pipe 30 adapted to be closed by a valve 31-, this pipe being adapted to be readily connected and disconnected with a discharge pipe 32.

Between the several partitions or opening out of each chamber at the bottom are outlet pipes 23, the several outlets being controlled by valves 34 and all leading to a dischar e pipe 35 which is adapted to be readiIy coupled and uncoupled with connections to Entering the front 15 of the casing are a series of naphtha and steam pipes 36. These rest upon the channel bars to which they are secured by clips 37. These steam pipes within the casin have upwardly opening perforations and each connectsv with a naphtha and steam pipe 38 which is adapted to be readily coup e the source of naphtha and steam supply, each series of pi cs 36 being provided outside the head wit a valve 37 by which each series may be controlled. By providin the steam pipes with upwardly opening per orations t e packing of fine ground material in eliminating the naphtha is avoided as the and uncoupled with.

a suitable tank or steam pipe, not shown.

steam lifts the material so that the naphtha can be removed in less time and with less steam.

The tankage being placed in the chamber, the inlets 38 are coupled together. Naphtha is then forced through the inlet 38 and discharged into the caslng through a series of pipes 36 until filled. The valves 3a are then opened and the naphtha percolates through the mass of tankage in the chamber and extracts the grease, carrying it to the several chambers in the bottom of the casing from which it is drawn through the discharge pipe 35. The greased naphtha as it passes through the cloth and wire screen, prevents foreign matter from passing into the discharge chambers, and is of such material that it can be readily cleaned. The material in the casing is washed with naphtha as many times as may be necessary to remove all grease and the naphtha can be discharged into any particular section of the casing which may need additional treatment.

In determining when the material has been entirely freed from grease all the chambers at the bottom of the tank except one, are closed, and the naphtha or solvent coming from that chamber will determine whether the greasehas been entirely eliminated from the material above that particular chamber. Theoperation is repeated with each chamber until the solvent runs entirely free from the rease.

- A ter the fat has been washed out with the naphtha and drawn off, it is desirable to reclaim the naphtha remaining in the tankage. To accomplish this the naphtha valve (not shown) is closed and the steam valve (not shown) is openedand steam is admitted through the steam pipe 38 and into the several steam pipes 36 preferably opening the pipes at the bottom first, allowing the steam to enter each compartment forcing its way through the cloth and screen' and cleanin them of any material that has found lo gment, and gradually eliminating the naphtha from the mass from the bottom to the top. By separating the bottom into chambers the full force of the steam may be discharged into each so that each chamber may be completely cleared. The steam collects the naphtha, and passes off through the outlet pipe 30 to a suitable condensing chamber which is not shown. After the material is fully freed from naphtha, the inlet and outlet pipes are disconnected and the casing rotated on its bearings, and so that the contents may be readily discharged through the man-holes 10 and 11. When discharged the casin may be readily cleaned for further use. he channel bars and I beams not only support the steam pipes and brace the chamber, but partially support the material in the casing and prevent its acking after becoming saturated with nap tha.

'claim:" 1. A percolator comprising a cylindrical casing adapted to be revolved, an outlet pipe at the top, and a series of discharge pipes at the bottom, a plurality of perforated pipes arranged in series and directly entering through one end of the casing, and means for independently controlling each series.

2. A percolator comprising a cylindrical casing adapted to be revolved, longitudinally arranged channel irons extending from end to end of the casing, inlet and outlet pipes, and perforated naphtha and steam pipes entering through one end of the casing and resting upon the upper edges of said channel irons.

3. A percolator comprising a cylindrical casing adapted to be revolved, longitudinally arranged channel irons, inlet and outlet pipes, and naphtha and steam pipes entering through one end of the casing and resting upon the upper edge of said channel irons, the said naphtha and steam pipes having upwardly opening perforations.

4. A percolator comprising a cylindrical casing adapted to be revolved, longitudinally arranged channel irons extending from end to end of the casing, transversely arranged beams on which the channel irons rest, inlet and outlet pipes, and upwardly opening perforated naphtha and steam pipes entering one end of the casing and resting upon the upper edges of said channel irons.

5. A percolator comprising a cylindrical casing adapted to be revolved, brackets at opposite ends of said casing, longitudinally arranged channel irons secured at opposite ends to said brackets, inlet and outlet pipes,

casing adapted to be revolved, a series of partitions at the bottom forming a series of chambers, a perforated bottom restin on said partitions, an outlet at the top 0 the casing, discharge pipes from the bottom of each of said chambers, and perforated naphtha and steam pipes entering one end of the casing.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
